Abstract
A system and method for preventing hidden data being passed using steganography by performing additional steganography to obscure the hidden data such that the hidden data is unrecoverable without information regarding the method of the additional steganography. This system and method allows for preventing hidden data without having to decipher the hidden data.
Claims17
A system, comprising:
- a non-transitory memory storing instructions;
- and
- one or more hardware processors coupled to the non-transitory memory and configured to read the instructions from the non-transitory memory to cause the system to perform operations comprising:
- receiving a media file over a network communication;
- identifying the media file based on a checksum and/or a hash of the media file:
- detecting that a first steganography has been applied to the media file based on encoded information of the media file including the checksum or the hash of the media file;
- and
- applying, based on the encoded information of the media file, a second steganography on the media file, the second steganography configured to remove the first steganography from the media file, wherein the encoded information includes instruction on the applying the second steganography on the media file to remove the first stenography from the media file.

A computer-implemented method, comprising:
- receiving a media file over a network communication;
- identifying the media file based on a checksum and/or a hash of the media file;
- detecting that a first steganography has been applied to the media file based on encoded information of the media file including the checksum or the hash of the media file;
- and
- applying, based on the encoded information of the media file, a second steganography on the media file, the second steganography configured to remove the first steganography from the media file, wherein the encoded information includes instruction on the applying the second steganography on the media file to remove the first steganography from the media file.
2 more elements
A non-transitory computer-readable medium having stored thereon instructions executable by a computer to cause the computer to perform operations comprising:
- receiving a media file over a network communication;
- detecting that a first steganography has been applied to the media file based on encoded information of the media file including a checksum or a hash of the media file;
- and
- applying, based on the encoded information of the media file, a second steganography on the media file, the second steganography configured to remove any steganography messages within the media file, wherein the encoded information includes instruction on the applying the second steganography on the media file to remove the first steganography from the media file.
